Both the consultants and ASA members agree that for neonates and infants, fasting from the intake of infant formula for 6 or more hours before elective procedures requiring general anesthesia, regional anesthesia, or procedural sedation and analgesia should be maintained. For healthy adults undergoing elective procedures with general anesthesia, regional anesthesia, or procedural sedation, what are the effects of chewing gum on residual gastric volume, gastric pH, and pulmonary aspiration before anesthesia induction?

Patients with conditions that can affect gastric emptying or fluid volume. chewing tobacco npo guidelines. Evidence concerning patient-reported outcomes comparing 1- to 2-h clear liquid fasting in children was limited to one or two studies per outcome. The history, examination, and interview should include assessment of ASA physical status, age, sex, type of surgery, and potential for difficult airway management as well as consideration of gastroesophageal reflux disease, dysphagia symptoms, other gastrointestinal motility and metabolic disorders (e.g., diabetes mellitus) that may increase the risk of regurgitation and pulmonary aspiration.

Benefits, Harms, and Strength of Evidence for 1-h versus 2-h Clear Liquid Fasting in Children. Placebo-controlled RCTs are equivocal regarding the efficacy of glycopyrrolate to reduce gastric volume or acidity (Category A2-E evidence),83,102 and two nonrandomized placebo-controlled comparative studies report equivocal findings the efficacy of atropine on gastric volume and acidity (Category B1-E evidence).103,104.
